At Axon Energies, we’re proud to announce a breakthrough that redefines how India charges its electric fleets: the successful unveiling of the country’s first fully off-grid 250 kW DC-to-DC charger.
Unlike conventional EV chargers that rely on grid-connected AC power, this new system bypasses all AC/DC conversion, directly utilizing DC power from solar PV arrays and battery energy storage systems (BESS). The result? Significantly higher efficiency, faster charge times, and true energy independence.
Why This Matters
India’s electric mobility transition is already well underway, but infrastructure remains a bottleneck—especially for high-capacity, high-turnover fleet hubs. Grid instability, land constraints, and diesel generator dependence continue to plague existing charging setups.
Our DC-to-DC charger solves these pain points by:
Enabling sub-30-minute rapid charging for electric buses and trucks
Operating entirely off-grid, powered by solar + BESS
Reducing transmission losses, thanks to a direct DC input/output architecture
Eliminating diesel gensets, making fleet charging 100% renewable
Minimizing infrastructure delays, with modular plug-and-play deployment
Built for the Indian Fleet Market
Designed from the ground up for India’s logistics and highway ecosystem, this charger is optimized for use at:
Way Side Amenities (WSAs) on national expressways
Multi-Modal Logistics Parks (MMLPs)
Intercity fleet depots and EV terminals
With capacity to charge 10 heavy-duty EVs simultaneously, and seamless integration with Axon’s proprietary Energy Management System (EMS), this prototype sets the stage for next-gen fleet electrification—scalable, decentralized, and emission-free.
What’s Next
We are now preparing pilot deployments across select PSU-operated highway locations and industrial freight hubs, with full-scale rollout expected in 2026. Our goal is to make this technology the standard for India’s fleet charging future.
Stay tuned for more updates as we take this innovation from prototype to nationwide deployment.
